The CCN clearinghouse provides a synthesized and curated set of coastal carbon data that promotes the sharing of open data, novel analyses, and collaboration opportunities. The synthesis is created by curating and merging publicly available data through an automated script. This report documents the success or failure of the automated synthesis process, documents changes, conducts QA/QC tests, and provides visualizations and summaries of data within the clearinghouse.

Database Overview
Currently, this synthesis contains 541 studies with soil carbon associated observations across 4078 sites and 16007 cores from around the world. Observations represent a 64 year timespan, from 1960 to 2024.
Cases where a core ID is present in the core-level table but not the depthseries.
Cases where a core ID is present in the depthseries table but not the core-level table.
The studies with uncontrolled attributes in essential tables are the following:
Cifuentes_et_al_2023_Panama, Cifuentes_et_al_2024_Nicoya, Morrissette_et_al_2023
This table provides a more detailed breakdown of these attributes and the values associated with them:

Depth Interval Checks
The following studies have cores with a max depth of NA or 0: Tully_et_al_2024, Poppe_et_al_2024, Nahlik_and_Fennessy_2016, Mbense_et_al_2016, Langston_et_al_2022, Agawin_et_al_1996, De_Iongh_et_al_1995, Holmer_et_al_2007, Townsend_and_Fonseca_1998, Van_Engeland_2010
Instances of multiple observations for the same interval within a unique core (and unique method ID) were found in the following 44 studies:

There are 4663 single-interval surface samples (max depth < 20cm) and 179 single-interval subsurface samples. There are also 644 large single-interval samples (ex. one representative (?) sample for 0-100cm depth).
The following 3 studies had at least one depth interval where the depth max was less than the depth min: Bezuidenhout_et_al_2011, DelVecchia_et_al_2014, Thom_1992
